Investigation of perioperative changes in sciatic nerve stiffness in patients with lumbar disc herniation using shear wave elastography: A longitudinal cohort study.
Article in Fukushima journal of medical science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThis study aimed to investigate changes in sciatic nerve stiffness in patients with lumbar disc herniation (LDH) using shear wave elastography (SWE) before and after diskectomy. In addition, we explored the relationship between preoperative sciatic nerve stiffness in the affected side and patient characteristics, leg pain severity, and numbness.
methodsWe assessed sciatic nerve stiffness in 27 patients with LDH (nine females, mean age 45.1±15.3 years) preoperatively and one week postoperatively after diskectomy using SWE. We also measured patient characteristics such as age, height, body weight, leg pain severity, and numbness surgery.
resultsWe found a significant decrease in sciatic nerve stiffness on the affected side postoperatively. However, there was no significant change on the unaffected side. In addition, preoperative nerve stiffness on the affected side correlated with preoperative leg pain intensity.
conclusionSciatic nerve stiffness on the affected side was decreased at one week postoperatively compared with preoperatively. In addition, sciatic nerve stiffness on the affected side was correlated with leg pain severity.
